from you post i understand that new zealand license is not valued much around the world.
I don't know why that should be your understanding. New Zealand is an ICAO member state and its licence is as valued around the world as any other ICAO licence, JAA included. All that I suggested was that jobs for newly qualified pilots are few and far between, irrespective of what licence they hold - hence your chances of securing a job in NZ would be small.
So far as the JAA is concerned, a NZ licence will be worth the same as any other ICAO licence (i.e. not very much) but that is a function of European protectionism rather than any fault with the NZ licence. Before being able to fly commercially within the JAA you would need a JAA licence and, whilst an ICAO licence will attract some credits, there will still be a lot of hoops to jump through, not least the theoretical knowledge examinations.
